What is the area of this polygon?
units²

5-sided polygon on a coordinate plane with vertices F, N, S, C, W. Point f is at (negative 4, negative 2), point N is at (2, 4), point s is at (5, negative 2), point c is at (5, negative 4), and point w is at (negative 4, negative 4)

Answers

Step 1) Draw a line from point F to point S. A rectangle forms (rectangle FSCW)

Step 2) Find the area of this rectangle. The area is 18 square units because it is 2 units high and 9 units across (9*2 = 18). You can count out the spaces or you can note how we go from x = -4 to x = 5 so subtracting the values gives -4-5 = -9 which has an absolute value of 9.

Step 3) Find the area of triangle FSN. The base is 9 units and the height is 6 units (count out the spaces or subtract y values). So the area is A = b*h/2 = 9*6/2 = 54/2 = 27

Step 4) Add up the area of the rectangle to the area of the triangle: 18+27 = 45

Final Answer: 45 square units

note: another way to find the answer is to find the area of rectangle WABC where point A is at (-4,4) and point B is at (5,4). Then subtract off the triangular areas of AFN and BNS

In this exercise we have to use the knowledge of polygon area to calculate the area of a trapezoid, in this way we find that:

[tex]45 units[/tex]

So find the area of this rectangle, this area will be:

[tex]9*2 = 18[/tex]

Find the area of triangle FSN, this area will be:

[tex]A = b*h/2 = 9*6/2 = 54/2 = 27[/tex]

Sum all the areas will be:

[tex] 18+27 = 45[/tex]

Write an equation of te circle with the center (0,0) and radius square root of 15

Answers

Answer:
x² + y² = 15

Explanation:

The formula for the equation of a circle is (x - h)² + (y - k)² = r², where the center of the circle is ordered pair (h, k) and r represents the radius (in units).

Now, we plug the given information into the circle equation and simplify.
radius = √15
center (0, 0), h = 0, k = 0

(x - 0)² + (y - 0)² = (√15)²
(x)² + (y)² = (√15)²
x² + y² = 15

The equation of the circle is x² + y² = 15

The equation of the circle with a center at (0,0) and a radius of the square root of 15 is x² + y² = 15. The standard form of the circle equation, (x - h)² + (y - k)² = r², is used with h and k set to 0 to represent the origin.

To write an equation of a circle with the center at the origin (0,0) and a radius of the square root of 15, we use the standard form of the circle equation:

(x - h)² + (y - k)² = r²

Here, (h, k) represents the center of the circle and r is the radius. Since the center of the circle in question is at the origin, h = 0 and k = 0. The given radius is the square root of 15, so we have r = √15. Substituting these values into the standard form gives us the equation:

x² + y² = ( √15 )²

Which simplifies to:

x² + y² = 15

This is the equation for the desired circle centered at the origin with radius √15.

When Mr. Peters drives from Boston to Worcester it takes him 30 minutes travelling at a speed of 60 miles per hour. Mrs. Peters drives from Boston to Worcester and leaves 5 minutes after Mr. Peters but travels at a speed of 90 miles per hour. Who will arrive first? By how many minutes?

Answers

Since the problem is requesting the answer in minutes, we are going to convert the speed of Mr. Peter to miles per minutes; to do that, we are going to multiply his speed by the multiplier [tex] \frac{60min}{1h} [/tex]:
[tex]60 \frac{miles}{h} * \frac{1h}{60min} =1 \frac{mile}{min} [/tex]

Now, to find the distance from Boston to Worcester, we are going to use the distance formula: [tex]d=vt[/tex]
where
[tex]d[/tex] is the distance
[tex]v[/tex] is the speed
[tex]t[/tex] is the time

We know that the speed of Mr. Peter is [tex]1 \frac{mile}{min}[/tex] and his time is 30 minutes. Lets replace those values in our formula:
[tex]d=1 \frac{mile}{min} *30min[/tex]
[tex]d=30miles[/tex]

Now, lets concentrate on Mr. Peter clone, Mr. P:
Lets convert the speed of Mr. P to miles per minute:
[tex] \frac{90miles}{h} * \frac{1h}{60min} =1.5 \frac{miles}{min} [/tex]
We also know that they will cover the same distance, 30 miles. Lets replace the values in our formula one more time to find t:
[tex]d=vt[/tex]
[tex]30miles= 1.5\frac{miles}{min} *t[/tex]
[tex]t= \frac{30miles}{1.5\frac{miles}{min}} [/tex]
[tex]t=20min[/tex]
But since Mr. P leaves 5 minutes after Mr. Peters, we need to add those 5 minutes to M. P's time:
[tex]t=20min+5min[/tex]
[tex]t=25min[/tex]

We can conclude that Mr. P will arrive first, 5 minutes before Mr. Peter.

Mrs. Peter arrives 5 minutes before Mr. Peter

To find who arrives first we first need to find the speed and time they require to arrive.

Given : From Boston to Worcester

Mr. Peter takes [tex]\rm time=30 \; minutes \; and \;speed= 60 miles /hr[/tex]

Mrs. Peter takes [tex]\rm speed=90 miles/hr[/tex]

We will now calculate Mr. Peters speed,

[tex]\rm 60 \dfrac{miles}{h} \times \dfrac{h}{60minutes}=\dfrac{mile}{min}[/tex]

How to find distance from Boston to Worecester?

To find the distance, we will use distance formula

[tex]\rm Distance=speed\times time[/tex]

Here,given that the Mr Peters speed is [tex]\rm 60 miles /hr[/tex] and time is [tex]\rm 30 minutes[/tex]so by distance formula we will find distance of Mr. Peter

[tex]\rm Distance=\dfrac{mile}{min} \times 30 minutes[/tex]

[tex]\rm Distance= 30 miles[/tex]

Similarly, we will now calculate Mrs. Peters speed,

[tex]\rm \dfrac{90miles}{h} \times \dfrac{h}{60minutes}=1.5\times \dfrac{miles}{min}[/tex]

by the given informations we know both covers the same distance

[tex]\rm ie. \;30 miles[/tex]

we will now find distance of Mrs. Peter

[tex]\rm Distance=speed\times time\\ 30miles=1.5\dfrac{miles}{min} \times time\\ time=\dfrac{30miles}{1.5\dfrac{miles}{min}}\\\\ time=20 minutes[/tex]

Here, we know that Mrs.Peter leaves from Boston to Worcester 5 minutes after Mr.Peter so we will add 5 minutes to Mrs. Peters time.

[tex]\rm time=20 minutes+ 5 minutes\\ time=25 minutes[/tex]

Therefore, it is clear that Mrs.Peter arrive before Mr Peter by 5minutes.

This question is about finding the slope of the tangent line to an inverse function. I would love to know if my answer of 1/5 is correct.

g(1) = 2
g^-1(2) = 1

(g^-1(x))' = 1/(g'(g-1(x))
(g^-1(2))' = 1/g'(g-1(2))
(g^-1(2))' = 1/g'(1)

g(x) = x^3 + 2x - 1
g'(x) = 3x^2 + 2
g'(1) = 3+2=5
(g^-1(2))' = 1/5

Answers

Yes choice B) 1/5 is correct. You are using the correct formula and steps. Nice work.

Here's another way to look at it:

When you visually plot the inverse, you reflect everything over the line y = x. What happens is that every (x,y) point swaps coordinates. So if (1,2) is on g(x), then (2,1) is on the inverse, and vice versa. Swapping the x and y values will swap the nature of the tangent slope.

For any tangent on g(x), its slope is m = (dy)/(dx)

The corresponding slope on the inverse will be n = (dx)/(dy). All that's happened here is that the numerator and denominator flipped. Again because x and y have swapped places. If you wanted, you can picture the xy axis where the vertical axis is the x axis and the horizontal axis is the y axis. That's effectively what is going on here.

So before you found that g'(1) = 5 meaning that m = 5/1 on g(x) at the point (1,2)
So n = 1/m = 1/5 for the point (2,1) on the inverse g function.

A certain number of bacteria are in a petri dish. If the growth rate is 2.7 percent per hour, how many hours will it take the bacteria to double in number?

Answers

Final answer:

Using the rule of 70, which states that the doubling time in hours is equal to 70 divided by the growth rate percentage, it will take approximately 25.93 hours for the bacteria to double in number at a growth rate of 2.7 percent per hour.

Explanation:

To calculate the time it will take for the bacteria to double in number with a growth rate of 2.7 percent per hour, we can use the rule of 70. The rule of 70 states that we can find the doubling time by dividing 70 by the percentage growth rate.

Doubling time = 70 ÷ growth rate percentage = 70 ÷ 2.7 ≈ 25.93

Therefore, it will take approximately 25.93 hours for the bacteria to double in number.

Jeanine baker makes floral arrangements. she has 18 different cut flowers and plans to use 7 of them. how many different selections of the 7 flowers are possible?

Answers

Final answer:

Jeanine can create 43758 different floral arrangements using 7 flowers out of the 18 available. This was calculated using the mathematical concept of combinations.

Explanation:

To find the number of different selections of 7 flowers Jeanine can make out of 18, we need to use the mathematical concept of combinations. In this context, the combination formula is used, which is: C(n, k) = n! / [k!(n-k)!]

Where n is the total number, k is the number chosen, and '!' stands for factorial, which is the product of all positive integers less than or equal to the number. Thus, the number of ways Jeanine can choose 7 flowers out of 18 is calculated as follows: C(18, 7) = 18! / [7!(18-7)!] = 43758. Therefore, there are 43758 different ways Jeanine can create floral arrangements using 7 flowers out of the 18 available.

It should be noted that the color of the flowers does not influence the number of combinations if she intends to select any 7 flowers irrespective of their color.

QS is the perpendicular bisector of PR solve for x

Answers

2x - 20 = 70 - x

3x - 20 = 70

3x = 90

x = 30

Final answer:

The term 'perpendicular bisector' means QS cuts PR into two equal parts at a 90-degree angle. If PR is '2x', then each half is 'x'. To solve for x, we would need data about the lengths of the line segments.

Explanation:

Given that QS is the perpendicular bisector of PR, it implies two things. Firstly, QS intersects PR at a 90-degree angle. Secondly, QS splits PR into two equal segments. So, if PR is represented as '2x', then PQ and QR are both 'x'.

Unfortunately, missing information prevents a specific solution for x. We'd need additional data about the lengths of these line segments to solve the equation for x. For instance, if PR = 10, then '2x = 10' which gives us 'x = 5'.
